can you know who is visiting your facebook?

Facebook made it very clear: they DO NOT notify a person when their pictures or profile has been viewed, when, how often and by whom. There is NO WAY for this information to become available.

Some people have jumped on this opportunity to create third party APPS which claim to show you who has been viewing your profile. But, as Facebook makes this impossible, the only way for those apps to work is if both the visitors of a profile and the profile owner have the same app installed. But that's a bad idea, since the application author's goal is to collect as much private information as possible, and sell it - names, e-mails, contacts, whatever the app can get from your profile when you add it.
